Hello, As you know, we have defined a supported database strategy, found here: http://dev.xwiki.org/xwiki/bin/view/Community/DatabaseSupportStrategy At the moment, in our release notes, we report the supported list of databases in the "Tested Databases" section. This is a little bit misleading, because we don't perform a full manual test on each of them. Also, at the moment, we don't have automated tests running on these databases. What I currently do is to test migration on each databases from an older version (in my case, I am using 2.7.2) to the current upcoming release. I usually perform these tests before RC1 so we make sure issues won't slip in the final release. Also, this testing is done on vanilla wiki's, so they don't reflect or simulate a large wiki migration with thousands of users and pages. What I want to propose is: 1) improve the "Tested Databases" section, so we list that we only test migrations and we don't perform a full test on each of the databases. This would mean adding a small explanation about this in the release notes pages. 2) When we release a new version, migrate myxwiki.org to the latest version, so users using it can report possible issues due to migration. This is a little hard for me to do since if something goes wrong, I could break a lot of things. Someone with more experience should do it, if there volunteers. I am waiting your feedback about this since I want to improve the visibility of testing, and also try to test migrations in a more real world environment Regards, Sorin B.
